South Suburb Prison in Anhu City was a newly constructed prison with an extensive land area, also known as the Bottomless Prison. It housed Awakeners who were criminals, particularly those who were extremely vicious and powerful.
The more troublesome the individual, the lower they were held in the prison.
Several bishops of the Calamity Sect were kept in different locations on the fifth underground level.
Each entrance and exit required iris verification, and the high-strength alloy doors could withstand a full-strength strike from a Body-Shaping Peak Expert.
Along the corridors and external high walls, there were patrols of guards clad in prison uniforms. They were Awakeners, carrying new-style firearms that were only seen in laboratories.
